When you move an Extended item from the inventory, the icon follows your mouse up until you leave the bag frame, at which point it won't show but will still keep the item tied to the mouse. The icon should stick to the cursor as long as we're moving the item. This should likely use the Cursor library from Ellyb.

There is an issue in the Cursor module currently where the icon is not above all frames. I will have to fix before we use it for this issue.
